I think HP use their own version of system recovery or product activation so it might be something to do with that.
So, can you see the D: drive (system recovery file partition of the main HD)? According to the HP website, your model didn't ship with separate recovery disks either, so I assume that they did the same thing with yours as they did with mine - to partition off a D: drive in FAT32, just large enough to hold the recovery files. Alternatively, I suppose they may have put the recovery files in a hidden folder on the C: drive. Anyway, I can see this D: partition in Knoppix, but not the C:, and Knoppix assumes that the D: partition is hda1.
